Elmohardyia formosa sp. nov.

Diagnosis. Tergite 2 with narrow basal gray pruinose band and two posterolateral gray pruinose spots. Sternite 6 with two subapical protuberances and crest-like apex. Surstyli asymmetrical. Left surstylus strongly developed, about 2.4X longer than right surstylus, with apex curved outward. Right gonopod more developed than left gonopod. Phallic guide with a distinct dorsal groove.

Postcranium dark, gray-brown pruinose dorsally and gray pruinose laterally and ventrally. Antennae ( Fig. 62 ) with scape dark brown; pedicel dark brown to black, with four dorsal and five ventral bristles; postpedicel dark brown, lighter towards margin. LPP/WPP = 1.5. Labellum dark yellow. Thorax. Postpronotal lobe brown, gray pruinose. Scutum dark brown to black, brown pruinose. Notopleuron brown, gray-brown pruinose with six weak bristles. Scutellum dark brown to black, gray-brown pruinose, with inconspicuous bristles. Mesopleuron and mediotergite dark brown to black, gray pruinose. Wing. ( Fig. 63 ). Length 6.9 mm. LW/MWW = 3.4. LTC/LFC = 1.4. Membrane slightly more brown infuscated at base; almost entirely covered with microtrichia, except for cells bc, basal half of c, sc, small basal area of r1, r2+3 and r4+5, br, bm, basal half of cup and small basal area of anal lobe without or with very sparse microtrichia. Vein r-m placed just before basal third of cell dm. Vein dm-cu straight. Halter brown, except for yellow stem. Legs. ( Fig. 61 ). Coxae dark brown to black, gray pruinose. Fore and mid trochanters dark brown to black, hind trochanter dark yellow to brown. Femora dark brown to black with base and apex yellow, entirely gray pruinose posteriorly. Tibiae dark yellow to brown, gray pruinose. Tarsi dark brown to black. Pulvilli yellow. Abdomen. ( Fig. 64 ). Dark brown to black, gray pruinose on tergite 1, on a narrow band on the base of tergite 2 and on posterolateral spots on tergites 2–5; tergite 1 with four stout black bristles laterally. Tergite 6 and sternites 6, 7 as in Fig. 65 . Sternite 6 ( Fig. 66 ) with two subapical protuberances and crest-like apex. Syntergosternite 8 dark brown to black, shorter than tergite 5, brown pruinose anteriorly, gray pruinose laterally and posteriorly ( Fig. 64 ) and with small membranous area ( Fig. 67 ). Terminalia. Epandrium and surstyli yellow ( Fig. 68 ). Surstyli ( Figs 68–69 ) asymmetrical. Left surstylus strongly developed, about 2.4X longer than right surstylus, with apex curved outward ( Fig. 69 ); lateral view as in Fig. 70 . Right surstylus with acute apex ( Figs 69, 71 ). Subepandrial sclerite as in Fig. 72 . Right gonopod more developed than left gonopod, with truncated apex ( Fig. 73 ). Phallic guide ( Figs 74–75 ) with a distinct dorsal groove and three additional processes, two placed dorsally and one laterally (not visible in Fig. 74 ); all processes are visible in dorsal view ( Fig. 75 ). Phallus with subapical spicule ( Fig. 76 ). Ejaculatory apodeme as in Fig. 77 . Female. Similar to male, differing in the following aspects: Body length 6.4 mm. Head. Antennae with pedicel with three dorsal and three ventral bristles; postpedicel dark brown at basal one third, remaining dark yellow. Front facets enlarged. Wing. Length 6.8 mm. LW/MWW = 3.3. LTC/LFC = 0.8. Abdomen. Tergite 6 weakly brown pruinose dorsally, otherwise gray pruinose. Ovipositor. OL: 1.3 mm; PL: 1.1 mm; B: 0.3 mm. Base dark brown to black, weakly gray pruinose; small, subrounded. Piercer yellow with distal part shining, straight ( Figs 78–79 ).

Type Material. HOLOTYPE ♂: “ BRASIL, MA[ranhão], Riachão, Fazenda Altos, Armadilha Malaise” “ 18– 22.viii.2009, F. Limeira-de-Oliveira & M.B. Aguiar-Neto” “ Holotype ♂, Elmohardyia formosa Marques & Rafael ” ( CZMA). PARATYPE: same data as holotype (1♀ CZMA).

Holotype condition. Left wing detached, mounted on microslide. Terminalia placed in microvial with glycerin.

Etymology. From Latin, formosus = beautifully formed, refers to the specimens general appearance.

Distribution. Brazil: Maranhão (Cerrado Biome).

Discussion. Elmohardyia formosa sp. nov. is close to E. gowdeyi (Curran) due to the long left surstylus with its outward curved apex. Elmohardyia formosa sp. nov. differs from E. gowdeyi by tergite 2 showing gray pruinosity on a narrow band along the base and posterolaterally (entirely gray pruinose in E. gowdeyi except for a small spot of brown pruinescence posteromedially), by sternite 6 with two subapical projections (only one subapical projection in E. gowdeyi ) and right gonopod not reaching to the apex of the phallic guide (surpassing the apex of the phallic guide in E. gowdeyi ).
